METALLIC CLOSURE FOR BOTTLES, JARS, 86C.

SPECIFICATION forming part of Letters Patent No. 745,702, d t d D b 1,1903.

Application filed April 8, 1903. Serial No, 151,575. (No model.)

To all whom it may concern:

Be it known that I, ALFRED L. VVEISSEN- THANNER, acitizen of theRepublic of France,

and a resident of the city, county, and State of New York, have inventedcertain newand useful Improvements in Metallic Closures for Bottles,Jars, &c., of which the following is a specification.

My invention relates to metallic closures for bottles, jars, 620., andmore particularly to sheet-metal stoppers having a crown portion and asecuring-flange inclosingasuitable sealing medium adapted to be bentinto locking-contact with the shoulder formed near the mouth of thebottle or jar.

As heretofore constructed the crown portion of stoppers of the characterreferred to have a depending flange portion which incloses a sealingmedium and projects down more or less from the mouth of the bottle. Theflange portion is made of a separate ring of metal, the same beingslightly flanged at the top to overlie the crown and having a detachableconnection to enable it to be readily released from the bottle to removethe stopper. Stoppers of this construction have been found to bedefective for the reason that although the sheet metal from which theyare constructed is ordinarilyprovided-with a protective coating theedges of the metal, and particularly the lower edge of the flangeportion of the crown, are not protected and often become oxidized orcorroded to such an extent as to discolor and destroy the sealingmedium, and thus injure the contents of the bottle or vessel. Stoppersof this construction are also defective for the reason that the partsthereof are not secured together. When the stopper is released from themouth of the vessel, the parts of the stopper fall apart, and if thecontents of the vessel are confined under pressure the parts of thestopper are apt to fly in various directions.

M-y invention has for an object to provide a construction whereby thesedifficulties are overcome.

More particularly the main object of my invention is to so construct thecrown portion of the stopper that the unprotected edge thereof will notcome in contact with the sealing medium or with the mouth of the bottleor vessel; also to provide a construction whereby the parts of thestopper will not be separated and scattered in various directions whenthe stopper is removed from a. vessel the contents of which are confinedunder pressure.

These and other objects of my invention will more fully appear from thefollowing description.

My invention consists in the novel parts, improvements, and combinationsherein shown and described.

The ac-com punying drawings, which are referred to herein and made apart hereof, ilius t rate two embodiments of my invention and serve, inconnection with the description herein, to explain the principlesthereof.

Of the drawings, Figure 1 is a side elevation of a stopper constructedin accordance with my invention, the same being shown as applied to themouth of a bottle. Fig. 2 is a plan view of the stopper removed from thebottle. Fig. 3 is a vertical central section of the same. Fig. 5 is asectional view, on an enlarged scale, illustrating a certain detail.Fig. 4 is a perspective view of the crown portion of the stoppen Fig. 6is a vertical central section illustrating a modification, and Fig. 7 isa perspective view of the crown portion of the stopper shown in Fig. 6.

In accordance with the embodiment of my invention illustrated in Figs. 1to 5, inclusive, the stopper consists of a crown portion 1, a flangeportion 2, and a suitable sealing medium 8. The crown 1 consists of adisk of metal, the same being suitably stiffened by having its outeredge folded over onto the top of the disk to form a bead or rim 4, asclearly shown in Fig. 4. The flange portion 2 consists of a band ofsheet metal having its ends 'detaehably secured by any suitable means,

as by a tongue 5, struck up from the metal of the band near one end andadapted to pass through an opening 6 near the other end of the band. Bypressing outwardly the exposed end 7 of the band the tongue 5 maybedisengaged from the opening 6, so as to release the band from the bottleor vessel.

Where the contents of the vessel are confined under pressure, thestopper as a Whole will be projected from the mouth of the hottle orvessel with considerable force, and if the parts of the stopper, andparticularly the metallic parts, are not so constructed that they willnot become detached as they are projected from the mouth of the bottlethey are apt to cause injury to surrounding objects or to the personopening the bottle. A thin metallic disk as the crown portion 1 would beespecially dangerous if it should become separated from the band portionand be projected at a high velocity. To overcome this objection to theconstruction as thus far described, the crown portion 1 of the stopperis secured to the flange portion. This may be accomplished in anysuitable way. As shown, the crown portion 1 is provided with a suitabletongue or projection 8, which is adapted to pass outwardly through anopening 9 in the flange portion 2, which opening in the particularembodiment of the invention shown is adjacent to the upper edge ofthefiange portion, said opening being preferably located on the linewhere the upper portion of the ring 2 is bent over to overlie the crownportion 1. The free end of the tongue 8 is bent over onto thetop of theflange 2, which overlies the rim of the crown portion 1, as clearlyshown in full lines in Fig. 5, said part of the crown portion beingslightly bent down into the recess formed between adjacent endsof therim 4.

In accordance with the construction in Fig. 6 the crown portion 10 isnot provided with a rim such as the rim 4 of the construction abovedescribed. Where the crown portion is not provided with anupwardly-turned rim, it is preferably formed of a non-corrosive metal,such as nickel or an alloy. The crown 10 is provided with a tongue 11,adapted to project through an opening 12 in the flange portion 2 of thestopper in a manner similar to that described in connection with theprevious form of the device. YVhere the crown portion of the stopper ismade of non-corrosive metal or where corrosion of the metal is notlikely to occur or if it occurs is not objectionable, the crown portionof the stopper may be provided with an integral depending flange, andthe connections between the crown and the securing-flange may be made atsome other point than at the point shown.

It will be seen that in each form ofv the device described there is nounprotected edge of corrosive metal so located as to come in contactwith the mouth of the bottle or with the sealing medium adjacent to themouth of the bottle. In the form of the device first described,moreover, there is no unprotected edge of metal which can come incontact with any portion of the sealing medium. The parts of thestopper, whether made of corrosive or non-corrosive metal, moreover, areso secured together that they will not be scattered when the stopper isprojected from the mouth of a bottle at a high velocity.

My invention in its broader aspects is not limited to the particularconstruction shown and described nor to the precise construction bywhich it may be carried into effect, as many changes may be made in theconstruction without departing from the main principles of the inventionand without sacrificing its chief advantages.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. A sheet metal stopper comprising a crown portion and a separateflange portion, said parts being so secured as not to be separated whenprojected from the mouth of a vessel.

2. A sheet metal stopper comprising a crown portion having anupwardly-turned rim and a separate flange portion having aninwardly-turned edge adapted to overlie said rim, substantially asdescribed.

3. A sheet metal stopper comprising a crown portion having anupwardly-turned rim and a separate flange portion having aninwardly-turned edge adapted to overlie said rim, said crown and flangeportions being so secured together as not to become separated whenprojected from the mouth of a vessel, substantially as described.

4. A sheet metal stopper comprising a crown portion having anupwardly-turned rim and a separate flange portion having aninwardly-turned edge adapted to overlie said rim, and means for securingsaid parts together, said means consisting of a finger on one partadapted to engage an opening in the other, substantiallyas described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ALFRED L. WEISSENTHANNER.
